Evaluation of three-dimensional setup errors using cone beam computed tomography (CBCT) for mediastinal lymphoma treated with volumetric modulated arc radiotherapy (VMAT) and deep inspiratory breath-hold (DIBH) technique
An asymmetric PTV margin of 1.0 cm longitudinally and 0.8 cm both anterior-posteriorly and laterally is adequate to cover setup uncertainties for patients treated with mediastinal radiotherapy using the DIBH technique at our center. The setup margins can further be reduced with daily image guidance and an online correction protocol.
